I've actually had the chance to ride on one of these, and it is impressive. Why? Well the biggest reason would be the real road feel to the whole system, it's so much closer to a set of rollers. The only negative is the noise, as the fan is VERY loud. But if you hate trainers this could be the one for you, as I don't like them but would happily spend some time on this. Price is still TBC but expect it to be around £400, which might be a factor in stopping world wide domination.
